This is a tense thriller that takes you inside the mind of a stressed out police officer assigned to call desk duty until he's potentially cleared of an unspecified violation that we only learn about near the story's finale. Officer Joe Baylor (Jake Gyllenhaal) takes the viewer on a roller coaster ride of emotional conflict as he tries desperately to save a woman he believes has been kidnapped by her estranged husband, while her two young children have been left at home to wait out the ordeal. Involving not only highway patrol, but fellow officers and a former sergeant, Baylor appears about to crack under the strain of not only the assumed kidnapping, but a six month old divorce that's still weighing heavily on his psyche. To say that things are not always as they seem in the picture would be quite an understatement, and the film's turning point hinges on a late phone conversation Baylor has with the unseen Emily (voiced by Riley Keough), which abruptly contradicts his original assumptions about a kidnapping. Gillenhaal brings all the intensity to his character that we've seen previously in his portrayal of Louis Bloom in "Nightcrawler". His performance here leaves you almost as emotionally drained as Joe Baylor, eventually willing to admit that the hearing he faces the next day must of necessity be handled with the utmost integrity.
